GAS OR OIL STOVE.

SPECIFICATION forming part of Letters Patent No. 637,231, datedNovemberl 21, 1899.

Original application led February 21, 1899, Serial No. 706,375. Dividedand this application iiled May 19, 1899. Serial No.

To a/ZZ whom, it may concern:

Be it known that I, EDWARD BURDEN, engineer, asubject of the Queen ofGreat Britain and Ireland, and a resident of Desboro Villa, Dysart road,Grantham, in the county of Lincoln, England, have invented certain new iand useful Improvements in and Relating to Gas or Oil Stoves, (for whichI have made application for Letters Patent in Great Britain, No.12,434,bearing date June 2, 1898,) of which the following is a specification,this application being a division of application Serial No. 706,375,filed February 21, 1899.

My invention relates to stoves, and has for its object to provide astove in which the air to support combustion is initially heated tosecure perfect combustion and a stove in which elective provision shallbe made for inducing circulation of air, so that thereby .warm air shallbe disseminated throughout the apartment in which the stove is placed.

My invention consists in the arrangement and design of a gas or oilstovein which the air for support-ing combustion is conducted from an orificeor'perforations in the outer casing at the upper part thereof downwardlyto an air-chamber situated at the lower part or base of the stove, suchair-chamber having a plate perforated so that the air may issue throughto the central space above where the burner or burners are provided, sothat the airin its downward passage may be heated by the radiant heatfrom the walls of the passage, so as thereby to insure perfectcombustion of the flame or flames and so obviate the dissemination ofdeleterious products of incomplele combustion that generally ensue inthe use of ordinary gas or oil stoves.

My invention is illustrated in the accompanying drawings, in which-Figures l and 2 are respectively side and front sectional elevations ofa stove in which a series of lue-tubes are employed.

In carrying my invention into eEect according to the figures I provide atube or flue I, of refractory material, or a series of such tubes I,which are suitably held in position upon the burner-chain ber FUandwithin the stove-casing E. The front face E14 of the casing isperforated for the admission of air, so as to pass in contact with theexterior of the tubesI, thereby becoming heated and passing down alongthe back of the burne'- chamber F', issuing from below to feed theflames. An air-circulating tube or space K3 may be provided along theback thereof, through which air may pass from the back of thestove-casing and issue out through the top L.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A gas or oil stove consisting of a central burner-chamber, anair-chamber above and at the rear thereof into which air passes from`the front of the outer casing said air-chamber discharging intotheburner-chamber above the burners, and a plurality of lluetubessuperposed upon the burner-chamber and within the air-chambersubstantially as described.

2. Agas or oil stove consisting of a central burner-chamber anair-chamber above and at the rear thereof into which air passes from thefront of the outer casing said air-chamber discharging into the burnerchamber above the burners, and a plurality of uetubes superposed uponthe burner-chamber and within the air-chamber, and air-circulating tubesat the rear of the air-chamber substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

EDWARD BURDEN.
